* Add craft-wordmodel: WordCraft's document model without its editing code WordCraft's crates/doc (wordcraft-doc, at 07f97737) moved as it is, so the DOCX, RTF, ODT and other text-format crates can read into and write from one model. Module paths, type names and serde attributes are unchanged: an app that re-exports the crate keeps its native file format. Left in the app: range editing (edit.rs), IME text and equation editing. Not model, and already in craft-libs: code pages (craft-rtf), the ZIP entry-count check (craft-opc), the compound-file guard (craft-cfb). The paragraph walks moved to walk.rs and the unit helpers of wordcraft-geom to geom.rs. * craft-wordmodel: math_tree, the arguments of an equation node and a walk over its runs The DOCX reader and writer walk an equation's runs. The walk and the child accessors it uses were in WordCraft's equation editor (math_edit.rs), which stays in the app; they are structure, not editing. * craft-wordmodel: keep the document operations (edit.rs) with the model The DOCX and RTF readers use them: alternative-format chunks are merged into a document with adopt_blocks, and a reader formats ranges with format_range and inserts objects. They operate on the document, not on a view, so they belong beside it. The tests that drove them come back with them; the paragraph walks stay in walk.rs and edit re-exports them. base64 0.23, as WordCraft and craft-offcrypto use.
